  1. 1. CRIS and OAR entities as LinkedData in scholarly communication –a vision scenario Jochen Schirrwagen Bielefeld University Library, Germany
  2. 2. About OpenAIRE - Motivation Implementation of a support infrastructure for the European Open Access pilot (2009-2012) Research Assessment – Identification, Capture, Measurement of EC funded FP7 project results (Special Clause 39) Addressing of Interoperability aspects regarding – European Commission (EC) Tools – Current Research Information Systems (CRIS)  JISC Research Excellence Framework – Open Access Repositories (OAR)2 London, 14th of July 2011 – Linked Data and Libraries
  3. 3. OpenAIRE facts Itself an EC funded FP7 project 38 OpenAIRE partners across Europe 27 National Open Access Liaison Offices 6887 projects in FP7 – Using CORDA as authoritative source Some 10.000 publications estimated Data-Sources (striving for OpenAIRE Guidelines compliancy) – Institutional repositories  Using OpenDOAR as authoritative source of ~850 repositories – Coverage of subject-based repositories planned – Coverage of OA journals planned3 London, 14th of July 2011 – Linked Data and Libraries
  4. 4. Interoperability Scenario CRIS CORDA Project data at Project data institution at EC KE-CRIS-OAR; PMH; ORE OpenAIRE Bibliographic Deposit/claiming data; DC; of publications OAI-PMH related to project OA-Repositories Author4 London, 14th of July 2011 – Linked Data and Libraries
  5. 5. Candidates for Entities & Vocabularies5 London, 14th of July 2011 – Linked Data and Libraries
  6. 6. Challenges – Data and Interoperability Capturing research output from different domains involves: Different responsibilities and tasks Different metadata formats used Different metadata exchange interfaces and protocols Different metadata granularity – In CRIS -> fine – In OAR -> coarse6 London, 14th of July 2011 – Linked Data and Libraries
  7. 7. Challenges – Data and Interoperability In the CRIS domain In the OAR domain – Covers the research process – Covers research publications – Run by the administrative – Run by the library department department – Focus on bibliographic quality – Broader view on research – Diverse metadata formats information  DC, DIDL/MODS, EPrints – Diverse data models and formats  CERIF (-like) models  DDF-MXD, METIS, PURE7 London, 14th of July 2011 – Linked Data and Libraries
  8. 8. Issues addressed by KE CRIS-OAR Working group within the quadrolateral Knowledge Exchange-Initiative (KE: SURF-NL, JISC-UK, DFG-DE, DEFF-DK) Aiming to increase interoperability between CRIS and OAR domains – Increasing metadata quality and re-use – Increasing level of interface standards – By taking existing formats into account:  Defining a metadata exchange format  With a corresponding set of common vocabularies8 London, 14th of July 2011 – Linked Data and Libraries
  9. 9. Publication entity as the center of interest Organisation Person Publication Event Project9 London, 14th of July 2011 – Linked Data and Libraries
  10. 10. How could “Linked Data” help ? Common way of linkages of content from distinct domains – Use of native web-technologies  Controlled vocabularies may help to tame semantic variability – URIfying named entities  Data publishers keep control of their data  Avoids context loss compared to interchange formats  May avoid double input and thus redundant data in each domain  Vocabulary helps to tame semantic variability May reduce the identifier problem by assigning persistent URIs to the entities – Person (Author) identifier (DAI, ORCID) – Publication identifier (DOI, URN, …) – Project identifier (?) – Event identifier (?) – Organisation identifier (?)10 London, 14th of July 2011 – Linked Data and Libraries
  11. 11. Aggregation of Interlinked Data Task to be addressed: – “bulk import/export” of publication and project data -> new wording “exposure” – Representing different views on the information packages, e.g.:  Publication as an Aggregation of Person, Organisation, Project and Event entities  Nested aggregation as a collection of all publications, where each publication is itself an aggregation of relative CRIS-OAR entities11 London, 14th of July 2011 – Linked Data and Libraries
  12. 12.

  13. 13. Extract of a ORE RDF Serialization13 London, 14th of July 2011 – Linked Data and Libraries
  14. 14. Next Steps Adopting KE CRIS-OAR model and vocabulary Addressing “Linked Data” in OpenAIREplus starting in 12/2011 – Linkage of publications and research data – Linkage of CRIS and OAR domains Further scenarios may include linked data as citations or statistical data14 London, 14th of July 2011 – Linked Data and Libraries
